Muscle question: agonist vs. synergist An agonist muscle is the primary mover, the one doing the work. An antagonist muscle is the opposite muscles. As one contracts the other will lengthen. Ex: Bicep curls - the Biceps brachii (shortening, contracting, concentric) would be the agonist and the triceps brachii (lengthening, relaxing, eccentric) would be the antagonist. A synergist would be the brachialis. (That is just one example). A synergist muscle(s) is a helper muscle(s)- they assist the primary with doing the work.....

Difference Between Agonist and Antagonist Agonist works when the muscles relax and antagonist works when muscles contract. Agonists can be called as ‘prime movers’ as these very much responsible for producing specific movements. Agonist is a substance, which combines with the cell receptor to produce some reaction that is typical for that substance.

antagonist antagonist. 1. a muscle that counteracts the action of another muscle, its agonist. 2. a drug that binds to a cellular receptor for a hormone, neurotransmitter, or another drug blocking the action of that substance without producing any physiological effect itself.ntagonist. 1. a muscle that counteracts the action of another muscle, its agonist. 2. a drug that binds to a cellular receptor for a hormone, neurotransmitter, or another drug blocking the action of that substance without producing any physiological effect itself.

Anatomical terms of muscle Agonist muscles cause a movement to occur through their own contraction. For example, the triceps brachii contracts during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while relaxing.ntagonist muscles oppose a specific movement. This controls a motion, slows it down, and returns a limb to its initial position. Antagonism is not an intrinsic property; it is a role that a muscle plays depending on the motion. If a motion is reversed, agonist and antagonist muscles switch roles.

agonist muscle agonist muscle prime mover (see agonist). antagonist muscle muscles or muscle groups which neutralize action of another muscle or muscle group (see antagonist; muscle contraction).cardiac muscle; myocardium striated heart muscle.ontrolled movements involve two opposing muscles: the agonist muscle produces the main action, while the antagonist muscle produces the opposite action to a lesser degree. The balance between agonist and antagonist muscles allows precise control of the final action. See also: muscle.

antagonistic muscles an·tag·o·nis·tic mus·cles. two or more muscles that produce opposite movements (function), the contraction of one having the potential, in theory, to neutralize that of the other; however, in so doing, they are frequently acting as synergists in fixing the moving part.

- Agonist: A substance that acts like another substance and therefore stimulates an action. Agonist is the opposite of antagonist. Antagonists and agonists are key players in the chemistry of the human body and in pharmacology.

What are the antagonist,agonist, and the ... Let me try again. An agonist is a prime mover, while antagonist is a muscle whose action is the direct opposite of that of agonist. The gluteus medius muscle is the prime mover responsible for hip abduction. It is an agonist.The hip adductor muscles are the antagonists to the glutues medius.

- Antagonist. An antagonist is a muscle that is capable of opposing the movement of a joint by producing torque that is opposite to a certain joint action. This is usually a muscle that is located on the opposite side of the joint from the agonist.s stated above, agonist muscles are muscles that are responsible for causing a certain joint motion. However, the term is often defined incorrectly to mean ALL the muscles that have a role in producing a movement. By this definition stabilizers, neutralizers, and fixators are also agonists. This is incorrect.

Anatomical terms of muscle Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract-the triceps relaxes while the biceps contracts to lift the arm.Reverse motions need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs.gonist muscles cause a movement to occur through their own contraction. For example, the triceps brachii contracts during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while relaxing.

Extraocular Muscles and Movements An agent that acts in physiological opposition: a muscle that contracts with and limits the action of an agonist with which it is paired—called also antagonistic muscle. 4 The short version of these formal definitions can be reworded as an agonist muscle being the muscle that works to achieve a desired action (e.g. looking left), while an antagonist muscle exists to perform the opposite action (e.g. looking right).

FULL AGONISTS, PARTIAL AGONISTS, ANTAGONISTS Three types of opioids are classified by the effect that they have on the mu receptors on cells. They are the full agonist, the partial agonist and the antagonist. As used here, an agonist is something that stimulates or produces an effect. Agonist is derived from the Late Latin agnista which means contender which is derived from the Greek agonists which also means contestant which came from agon which means contest. An agonist is a chemical contestant or contender.
